Filter data on form with TempDB data source

Hello

I have a form with following functionality

The form has 5 data sources with TempDB tables which are not joined to each other. The data source data is displayed on 5 separate grids.

When the form opens, the data needs to be populated on the form. There is a custom Save button and clicking on it, data needs to be copied from all of these individual data source and stored in a seperate regular table one for each of these tempdb datasources. The save can happen multiple times and data can be stored in the table for every new version which is unique by a number.

there is another form control with drop down on these versions. when a user picks a specific version the data needs to be loaded on the form for that specific version.

I am adding code to populate the temp table on modified event and calling research method. But the data on the form does not reflect on what I populate in code, eventhough I populate the datasource for that specific version.

Hi SKO,

Can you share your coding and screenshots of the current behavior? That will help in understanding what exactly you try to achieve.

I am looking for code to clear the grid data and update it as per the input parameters.

[DataSource] class ProdOrderTmp { /// <summary> /// /// </summary> public void init() { if (rev) { this.loadProdOrderTmp(); } super(); } //When form opens load the temp table grid from saved data public void loadProdOrderTmp() { ProdOrderTmp prodOrdersTmp; Prodorders prodorders; while select prodorders { prodOrdersTmp.clear(); prodOrdersTmp.Rev = prodorders.Rev; prodOrdersTmp.ProdId = prodorders.ProdId; prodOrdersTmp.Description = prodorders.Description; prodOrdersTmp.insert(); } ProdOrderTmp.linkPhysicalTableInstance(prodOrdersTmp); } public void executeQuery() { delete_from prodOrdersTmp; while select prodorders where prodorders.rev == rev { prodOrdersTmp.clear(); prodOrdersTmp.Rev = prodorders.Rev; prodOrdersTmp.ProdId = prodorders.ProdId; prodOrdersTmp.Description = prodorders.Description; prodOrdersTmp.insert(); } super(); } on the Form control, here is the parameter field. When the field value changes, the data on form grid should change accordingly. i,e clear the grid and update with data related to the parameter public boolean modified() { boolean ret; ret = super(); rev = this.value(); ProdOrderTmp_ds.executeQuery(); return ret; }

In your above code I don't see research method. Where are you calling it ?

I was able to achieve this by using only one tempdb buffer for each temp table for all operations and linking it in Datasource Init() using the below call specifically after the super()

ProdOrderTmp.linkPhysicalTableInstance(prodOrdersTmp);
